Answer:
A = $2200(7.612) = $16,747.28
Step-by-step explanation:
You don't say whether this is simple interest or compound interest. I will assume you meant compound interest, for which the appropriate formula is
A = P(1 + r)^t, where P is the principal amount, r is the interest rate as a decimal fraction, and t is the time in years. Then:
A = $2200(1 + 0.0725)^29, or
A = $2200(1.0725)^29, or
A = $2200(7.612) = $16,747.28
Answer:
x= 127/8
Step-by-step explanation:
The greatest common factor for these two numbers is 6 because if you divide 24 by 6 you get 4 and if you divide 84 by 6 you get 14.
Answer: x= 24 degrees
y = 66 degrees
Step-by-step explanation:
In order to solve for x and y as given in the diagram, we would apply the following rules
1)The sum of the angles in a triangle is 180 degrees.
2) sum of angles in a straight line is 180 degrees
Looking at the bigger triangle on the left, let the last unknown angle be z
70 degrees + 74 degrees + z degrees = 180 degrees.
z = 180 degrees - 74 degrees - 70 degrees = 36 degrees.
Looking at the straight line at the bottom, it contains angle z( 36 degrees) , angle y and 78 degrees.
Therefore
36 degrees + y degrees + 78 degrees = 180
y = (180 -36 -78) degrees
y = 66 degrees
x + y(66 degrees) + 90 degrees = 180
x = (180 -66-90) degrees
x = 24 degrees
Answer:
Center: (-7, -4)
radius = 4
Explanation:
- Equation: (x + 7)² + (y + 4)² = 16
Circle formula:
(h, k) denotes the center of the circle, "r is radius"
Rewrite the following equation in standard form:
- (x - (-7))² + (y - (-4))² = 4²
From this identify:
- h = -7, k = -4, radius = 4
